Questions
How big is the Panel PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Panel use?
91 parts, built around the RP2040, W25Q32JVSSIQ, SP3485EN-Y and WS2812B. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Panel KiCad files?
From the dj505/Pad-Light-Kit repository on GitHub, at the commit this page was made from: the board is Panel/Panel.kicad_pcb and its schematic Addons/Comms Controller/Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask dj505 before reusing the design.
